“…We calculated the average particle size obtaining a value of 104 ± 27 nm. These results are similar to those obtained by Mohamad, et al (2020) where the glutathione catalyzed nano-magnetite particles appeared as scales and spheres with a particle size in the range of 50 to 100 nm. These results are also similar to those obtained by other researchers (Shahid & Choi, 2020;Nurlilasari, et al, 2020).…”

In the last decade, magnetic nanomaterials have been widely used in the fields of chemistry, physics, engineering, and medicine due to their optical, magnetic, and conductive properties, and as contrast agents in magnetic resonance. Their influence in the treatment of cancerous tumors has been evaluated and has sparked great interest in its use in environmental repair systems such as magnetic absorbers that trap metal particles and some contaminants. Here we analyze the influence of process parameters to obtain magnetic nanoparticles under three chemical synthesis methods. Its morphological characterization was performed by scanning electron microscopy (SEM), its elemental composition by energy dispersive spectroscopy (EDS), and its structure by x-ray diffraction (XRD). Our results showed that the obtention method had a great influence as evidenced by the variability in nanoparticle sizes. It is worth highlighting that we obtained particles at a nanometric scale, especially Fe3O4 (magnetite) and Fe2O3 (maghemite) structures, with potential superparamagnetism properties that could open a wide range of future applications for the production of these materials at low cost and easy access.

“…6–8 Hence, efficient removal of TCH from polluted water is still a major concern for the scientific community. Numerous water treatment techniques such as adsorption, 9 bio-degradation, 10 electrolysis, 11 oxidation, 12 photocatalysis 13,14 and the Fenton reaction 15 have been implemented to resolve the issues caused by TCH in wastewater. Due to the cost-effectiveness, ease of operation and paucity of secondary contamination, photocatalysis has been recognised as a viable approach for TCH extraction from polluted water.…”
